Audio 3000 specializes in the repair of vintage classic two channel stereo receivers. Pioneer, Marantz, McIntosh, Sansui and Kenwood are just a few of the units collectors are familiar with and prefer over the newer, more complex units of today. People prefer the simplicity of operation found in these classic 2 channel receivers. Amplifier bias and offset adjustments along with FM alignment checks are standard on all repairs. We recently decided to work on surround sound receivers, if parts and schematic diagrams are available.Contact us today to get started!
